Abstract

The utility model relates to a rotation steam type cymbopogon goeringii puffing apparatus. A main body of the utility model is composed of a circular cylinder body, an inner cone, partition plates, an upper and a lower sealing heads, a charging hole, a discharging pipe and a steam pipe, wherein, the inner cone is inverted at the lower part of the circular cylinder body; the partition plates which are in the shape of vortex are respectively welded with the steam pipe, the inner cone, the discharging pipe, the circular cylinder body, and the lower sealing head. All the interfaces outside a puffing apparatus body are connected with a valve. The utility model does not only can make the device more stable when cymbopogon goeringii is sprayed and puffed, the noises of vibrations can be reduced, etc. Because the utility model is provided with the partition plates which are uniformly arranged in a vortex shape, steam is led in the vortex shape, the cymbopogon goeringii is free from turning over, the cymbopogon goeringii is uniformly cooked and pressed, the time for cooking is shortened, the effects of hydrolysis with fibers can be obviously improved, the loss of short fibers is reduced, the yield of paper pulp can be enhanced by more than 5 percents.

Description

Rotation steam type tangerine grass puffing apparatus

(1) technical field

The utility model relates to a kind of rotation steam type straw grass puffing apparatus, belongs to the energy-conserving and environment-protective field of pulping technique equipment non-chemically.

(2) background technology

At present, the main method of tangerine bar and careless class pulping and paper-making all is to adopt chemical method, and the waste liquid amount that these class methods produce when being used for slurrying is big, difficult treatment, and environmental pollution is serious, and ecological environment especially water resource has been caused heavy damage.

Non-chemically pulping technique is because few, the pollution-free great attention that has been subjected to papermaking and environmental protection industry (epi) of water, the hot spraying tank that adopts is used for a kind of corollary equipment that ryegrass pulping is non-chemical pulping at present, reached certain effect, but this equipment is owing to the reason of steam supply formula, cause existence instability in the raw material digestion process, it is inhomogeneous to be heated, high-temperature residence time is short relative with the string removal time longer, short fiber runs off more, the not high phenomenon of paper pulp yield affects the raising of pulping technique non-chemically.

(3) summary of the invention

The purpose of the utility model design is a kind of rotation steam type straw grass of design puffing apparatus, changes the structure of prior art, increases in the middle of cone in rotation steam type tangerine grass puffing apparatus inner barrel and the cylindrical shell and revolves shape shape division board.

The rotation steam type tangerine grass puffing apparatus of the utility model design, mainly by cylindrical Shell, inner cone stop, charge door, discharge nozzle, steam pipe, division board form.Charge door, discharge nozzle lay respectively at cylindrical Shell up and down on the end socket at two ends, the funnel-form inner cone is welded on the interior below of cylindrical Shell, funnel-form inner cone end opening is the inside that discharge nozzle (also being trunnion) is sleeved on steam inlet, steam pipe outer wall and cylindrical Shell welding, division board 4-6 piece is welded on steam pipe equably, on funnel-form inner cone outer wall, the cylindrical Shell inwall, be the even distribution of swirl shape.

The utility model rotation steam type tangerine grass puffing apparatus adopts the discharge nozzle outer wall and garden tube inwall welding division board in the tube of garden, through the steam mouth of pipe and with its equal five equilibrium four or six parts, division board simultaneously and inner cone weld, division board is swirl shape and all distributes.The pore that all distributing on the funnel-form inner cone is for the importing of steam and the discharge of condensed water.Steam is the rotation shape by the swirl shape division board through the inner cone steam vent and imports in the tube of garden.This version has changed former equipment steam of the same type and has been imported by inner cone steam vent straight line and cause that the tangerine grass is subjected to the vertical up and down impact conditions shakiness of steam, the unequal shortcoming of being heated in the tube of garden, strengthened the time of contact and the area of steam and tangerine grass, made the boiling combination property obtain optimizing and improving.The utility model rotation steam type tangerine grass puffing apparatus has overcome the deficiency of equipment of the same type, has that digestion time shortens, the fiber hydrolysis effect obviously improves, short fiber runs off and reduces, paper pulp yield under equal conditions spurted the employed equipment of the same type of technology than former pressure and improve more than 5%.

(4) description of drawings

Fig. 1 is structural representation of the present utility model (the perpendicular figure that cuts open).

Fig. 2 is the cross-sectional figure at Figure 1A A place.

In conjunction with the accompanying drawings the utility model rotation steam type tangerine grass puffing apparatus is further described: among Fig. 1, Fig. 2: the 1st, steam pipe, the 2nd, discharge nozzle, the 3rd, division board, the 4th, pore, the 5th, take over, the 6th, garden tube end socket (upper and lower), the 7th, charge door, the 8th, garden cylindrical shell, the 9th, inner cone.As shown in drawings, the rotation steam type tangerine grass puffing apparatus of the utility model design, by garden tube 8, inner cone 9, division board 3, charging aperture 7, discharge nozzle 2, steam pipe 1, last low head 6 is formed.The bottom in the garden cylindrical shell 8 is inverted and is welded on to the inner cone that has a pore 4; Discharge nozzle 2 and inner cone 9 welded top are in the axis in the steam pipe 1, and steam pipe 1 is welded on the center of garden cylindrical shell 8 low heads, and is corresponding with the charge door 7 that upper cover 6 is welded; Division board four or six are swirl shape and are welded on respectively equably on steam pipe 1, inner cone 9 and the inner cone garden cylindrical shell 8 and low head 6 below 9; The external interface of puffing apparatus all is connected with valve.

(5) specific embodiment:

The utility model rotation steam type tangerine grass puffing apparatus is compared with other same category of device (as pressure blow tank, rotary spherical digester etc.) has following advantage:

1, the utility model rotation steam type tangerine grass puffing apparatus, owing to use the swirl shape division board, the steam Rotating with Uniform is entered in the tangerine grass, avoid stirring of tangerine grass, make it be subjected to boiling, pressurized is even, digestion time shortens, the fiber hydrolysis effect improves obviously, and short fiber runs off and reduces, and paper pulp yield can improve more than 5%.

2, the utility model mainly is welded by garden cylindrical shell, inner cone, division board, the center of gravity that has strengthened equipment moves down, and steam pipe, discharge nozzle, garden cylindrical shell are become one, and makes the tangerine grass quick-fried when expanded in spray, the utility model equipment is more stable, and the vibrations noise reduces.

Claims

1, a kind of rotation steam type tangerine grass puffing apparatus, it is characterized in that: this equipment is made of garden cylindrical shell, last low head, inner cone, division board, charge door, discharge nozzle, steam pipe.
